Abstract
The utility model relates to a pressure regulator which is composed of a main valve body 1, a connecting cavity body 2, a spring cavity body 3 and a safety valve 4, wherein, A valve seat 5 and a valve clack 6 at one end of a connecting rod 7 form a sealing pair, and the other end of the connecting rod is connected with a shifting fork 15. The other end of the shifting fork 15 is connected to the lower end of a connecting pull rod 16. The top of the connecting pull rod 16 is provided with a rubber film 17, one end of a pressure regulating spring 19 is used for pressing the rubber film 17, and the other end is the lower end of a regulating screw 18. The upper end of the regulating screw 18 is provided with a check nut 10, and the bottom of the connecting cavity body 2 is provided with the external safety valve 4. The utility model has the characteristics of simple and compact structure, small size, little flow quantity, high pressure regulating precision, effective and safe exhaustion, low cost, etc.
Description
The utility model relates to a kind of pressure governor, especially can have the pressure governor of safe bleeding device.
In the gas transmission process at natural gas transmission and distribution gas station, for the natural gas transmission and distribution with elevated pressures arrives the pressure that is fit to industrial gas or domestic gas, except adopting conventional pressure governor, also to consider to guarantee gas transmission safety simultaneously and not during gas-use low peak, pressure governor be proposed to damage the requirement of upstream device.At present, the pressure governor that occurs a kind of built-in safe bleeding device on the market when existing the distribution pressure setting, cuts out gas transmission system in advance, demolition spring inside cavity again, set, it sets complex process, also need align repeatedly, it is again built-in safe bleeding device, it is big to form volume, and flow is little, the deficiencys such as effort of taking a lot of work.
The purpose of this utility model provides a kind of pressure governor, and not only simple in structure, volume is little, and can when transmission ﹠ distribution have load, carry out pressure regulation, distribution pressure is set simple, and can discharge distribution pressure by effective and safe, set the pressure governor that also has safe bleeding device simply and easily.
The purpose of this utility model is to realize like this, by main valve body, connect cavity, the spring cavity, safety valve is formed, the one end valve lobe composition sealing pair of the connecting rod that its main valve body middle part valve seat with holes is interior with being connected cavity, the other end of connecting rod joins with group wooden fork, the other end of dialling wooden fork with is connected cavity interior vertical cylinder lever connecting rod lower end connection, glued membrane is arranged at the cylinder lever connecting rod top, the spring cavity has glued membrane with being connected between the cavity, pressure adjusting spring one end in the spring cavity is pushed down glued membrane, the other end is to adjust the screw lower end, adjust the screw upper end lock nut is arranged, connecting the safety valve that cavity bottom is provided with external, Safety valve body one end of the tubulose of safety valve be connected that cavity bottom is outer to be connected with seal washer, the other end joins with the adjustment screw and the lock nut of band exhaust port, is mounted with flap and spring in the Safety valve body.The utility model utilization is adjusted screw and is acted on pressure adjusting spring, pressure adjusting spring acts on glued membrane, cylinder lever connecting rod again, and cylinder lever connecting rod drives again dials wooden fork, connecting rod, makes flap open certain aperture, to reach the pressure of required gas transmission, remain by adjusting the constant voltage that screw is set up.Using under the glued membrane seal action between spring cavity and the connection chamber, make main valve body when transport gas, also can carry out pressure regulation.When flap has breakage; make the screw forfeiture pressure regulation effect of adjusting; or upstream device surpasses when bearing delivery pressure behind the valve; will be from the adjustment screw of the flap of safety valve, spring, band exhaust port rapidly automatically with the gaseous emission of superpressure; in the hope of protection upstream device safety; when pressure governor recovery proper functioning or discharge pressure reached the force value of setting, safety valve will cut out rapidly automatically, recovers the work of normal transmission ﹠ distribution gas.
The utility model compared with prior art, has simple and compact for structurely, and volume is little, and flow is big, pressure regulation precision height, effective and safe discharging, characteristics such as cost is low.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a sectional structure schematic representation of the present utility model.
Among the figure: 1-main valve body 2-connects cavity 3-spring cavity 4-safety valve 5-valve seat 6-flap 7-connecting rod 8-exhaust port 9-adjustment screw 10-lock nut 11-spring 12-flap 13-Safety valve body 14-seal washer 15-and dials wooden fork 16-cylinder lever connecting rod 17-glued membrane 18-adjustment screw 19-pressure adjusting spring
As shown in drawings, an end valve lobe 6 that connects the connecting rod 7 in the cavity 2 is adjacent with the valve seat 5 of main valve body 1, the other end of connecting rod 7 is connected with group wooden fork 15, the other end and cylinder lever connecting rod 16 lower ends of dialling wooden fork 15 join, cylinder lever connecting rod 16 upper ends are adjacent with glued membrane, pressure adjusting spring 19 two ends of spring cavity 3 are adjacent with adjustment screw 18 bottoms with glued membrane 17 respectively, adjust screw 18 upper ends lock nut 10 is arranged, be provided with safety valve 4 outside connecting cavity 2 bottoms, safety valve 4 is by the adjustment screw 9 of band exhaust port 8, flap 12, Safety valve body 13, seal washer 14, lock nut 10, spring 11 is formed.
